Circuit Documentation

Summary

This circuit integrates a microcontroller (ESP8266 NodeMCU), a temperature and humidity sensor (DHT11), and a rain sensor. The ESP8266 NodeMCU is responsible for reading data from the DHT11 and the rain sensor, processing the information, and potentially taking action based on the sensor readings. The DHT11 provides ambient temperature and humidity data, while the rain sensor can detect the presence of raindrops.
